It's funny how people on MN view wages. Precious DC's should not have to work for NMW and miss out on their exciting weekend socialising. Who works in care homes, national trust coffee shops, nurseries, preschools? Who serves your children school lunch, books your dental appointments, changes the bed sheets in your mini break hotel? All these people work for little over minimum wage, most work antisocial hours, do they not deserve more?
It is perfectly possible to be campaigning on both (and more issues). This particular conversation is bout minimum wage hospitality jobs.
It sounds like shit conditions, tbh, OP. As plenty of others have said, split the days and increase the pay (and/or conditions).
What amuses (astounds? astonishes?) me in this type of conversation is why people are surprised that these vacancies aren't being filled. A basic grasp of economics coupled with a bit of current affairs knowledge will fill in all the blanks. So including, but not an exhaustive list: lack of vaccinations, rubbish hours, rubbish money, having to deal with shitty public, Brexit, pandemic, job insecurity meaning people aren't moving around.
One of the things that never fails to get my blood boiling is the insistence that poor people must be encouraged to work (for low pay) by reducing the amount of money they get in benefits or wages, whereas to attract good CEOs you have to pay an obscene amount otherwise they won't do it. Hopefully this situation is an indication that the tide is turning: when things are scarce they get expensive. Currently that seems to apply to hospitality staff. Are we seeing an increase in pay? nope. Good luck finding staff then.
It is notable that one of the things that improved the lot of peasants in (i think) the 14th century was the fact that the farm workers and drudges etc were decimated by the black death (nobles too but maybe not so much as they weren't all packed in hovels like sardines) and as a result they could negotiate better pay and conditions to till the fields and so on for the nobles. Maybe Covid-19 will be our black death?
