There shall not be considered as a day of unemployment, or as a day of sickness, with respect to any employee—

(ii) any day in any period with respect to which the Board finds that he is receiving or will have received annuity payments under the Railroad Retirement Act of 1974 [45 U.S.C. 231 et seq.], or insurance benefits under title II of the Social Security Act [42 U.S.C. 401 et seq.], or unemployment, maternity, or sickness benefits under an unemployment, maternity, or sickness compensation law other than this chapter, or any other social-insurance payments under any law: Provided, That if an employee receives or is held entitled to receive any such payments, other than unemployment, maternity, or sickness payments, with respect to any period which include days of unemployment or sickness in a registration period, after benefits under this chapter for such registration period will have been paid, the amount by which such benefits under this chapter will have been increased by including such days as days of unemployment or as days of sickness shall be recoverable by the Board: Provided further, That, if that part of any such payment or payments, other than unemployment, maternity, or sickness payments, which is apportionable to such days of unemployment or days of sickness is less in amount than the benefits under this chapter which, but for this paragraph, would be payable and not recoverable with respect to such days of unemployment or days of sickness, the preceding provisions of this paragraph shall not apply but such benefits under this chapter for such days of unemployment or days of sickness shall be diminished or recoverable in the amount of such part of such other payment or payments;

(iii) if he is paid a separation allowance, any of the days in the period beginning with the day following his separation from service and continuing for that number of consecutive fourteen-day periods which is equal, or most nearly equal, to the amount of the separation allowance divided (i) by ten times his last daily rate of compensation prior to his separation if he normally works five days a week, (ii) by twelve times such rate if he normally works six days a week, and (iii) by fourteen times such rate if he normally works seven days a week; ¹

(a–2) Day of unemployment

(i)

(A) subject to the provisions of subdivision (B) hereof, any of the days in the period beginning with the day with respect to which the Board finds that he left work voluntarily, and continuing until he has been paid compensation of not less than $1,500 with respect to time after the beginning of such period and before 1989 or, if any part of such compensation is paid in a calendar year after 1988, not less than an amount that is equal to 2.5 times the monthly compensation base for months in such calendar year, as computed under section 351(i) of this title;

(B) if the Board finds that he left work voluntarily with good cause, the provisions of subdivision (A) shall not apply, with respect to him, to any day in a registration period if such period does not include any day which is in a period for which he could receive benefits under an unemployment compensation law other than this chapter, and he so certifies. Such certification shall, in the absence of evidence to the contrary, be accepted subject to the penalty provisions of section 359(a) of this title;

(ii) any of the thirty days beginning with the day with respect to which the Board finds that he failed, without good cause, to accept suitable work available on such day and offered to him, or to comply with instructions from the Board requiring him to apply for suitable work or to report, in person or by mail as the Board may require, to an employment office;

(iii) subject to the provisions of subsection (b) of this section, any day with respect to which the Board finds that his unemployment was due to a stoppage of work because of a strike in the establishment, premises, or enterprise at which he was last employed, and the Board finds that such strike was commenced in violation of the provisions of the Railway Labor Act [45 U.S.C. 151 et seq.] or in violation of the established rules and practices of a bona fide labor organization of which he was a member.

(b) Participation, interest, or financial assistance in labor dispute
The disqualification provided in subsection (a–2)(iii) of this section shall not apply if the Board finds that—

(i) the employee is not participating in or financing or directly interested in the strike which causes the stoppage of work: Provided, That payment of regular union dues shall not be construed to constitute financing a strike or direct interest in a strike within the meaning of this and the following paragraphs; and

(ii) he does not belong to a grade or class of workers of which, immediately before the commencement of the stoppage, there were members employed in the establishment, premises, or enterprise at which the stoppage occurs, any of whom are participating in or financing or directly interested in the dispute: Provided, That if separate types of work are commonly conducted in separate departments of a single enterprise, each such department shall, for the purposes of this subsection, be deemed to be a separate establishment, enterprise, or other premises.

(c) Unsuitable work
No work shall be deemed suitable for the purposes of subsection (a–2)(ii) of this section, and benefits shall not be denied under this chapter to any otherwise qualified employee for refusing to accept work if—

(i) the position offered is vacant due directly to a strike, lockout, or other labor dispute;

(ii) the remuneration, hours, or other conditions of work offered are substantially less favorable to the employee than those prevailing for similar work in the locality, or the rate of remuneration is less than the union wage rate, if any, for similar work in the locality;

(iii) as a condition of being employed he would be required to join a company union or to resign from or refrain from joining any bona fide labor organization;

(iv) acceptance of the work would require him to engage in activities in violation of law or which, by reason of their being in violation of reasonable requirements of the constitution, bylaws, or similar regulations of a bona fide labor organization of which he is a member, would subject him to expulsion from such labor organization; or

(v) acceptance of the work would subject him to loss of substantial seniority rights under any collective bargaining agreement between a railway labor organization, organized in accordance with the provisions of the Railway Labor Act [45 U.S.C. 151 et seq.], and any other employer.

(d) Factors in determination of suitable work
In determining, within the limitations of subsection (c) of this section, whether or not any work is suitable for an employee for the purposes of subsection (a–2)(ii) of this section, the Board shall consider, in addition to such other factors as it deems relevant, (i) the current practices recognized by management and labor with respect to such work; (ii) the degree of risk involved to such employee's health, safety, and morals; (iii) his physical fitness and prior training; (iv) his experience and prior earnings; (v) his length of unemployment and prospects for securing work in his customary occupation; and (vi) the distance of the available work from his residence and from his most recent work.

(e) Voluntarily leaving unsuitable work
For the purposes of subsection (a–2)(i) of this section, no voluntary leaving of work shall be deemed to have been without good cause if the Board finds that such work would not have been suitable for the purposes of subsection (a–2)(ii) of this section.
