Could I check what others think of the following scenario?

An agency worker engagement ends early due to closure of an establishment in response to the Covid outbreak.  There is written agreement at the outset that the worker would receive 5 days notice should the engagement end earlier than expected.  Would the engaging organisation be obliged to pay the worker 5 days in lieu of notice?

I appreciate in general terms the agency worker would not be entitled to any payment...but the fact a notice period is included in the initial agreement is my concern.  It is possible Force Majeure may apply...but if the clause is not specific enough to cover current circumstances - I wondered if there may be an obligation to pay?

I have been swithering about this one all day and wondered if there may be someone out there who may have information or an opinion that would help in any way!

Cheers,
