In my workplace, I have heard that 'compensation' can be had for swapping a shift with someone. If that person is desperate enough to not work their own shift and they want yours, a cash amount could be offered, or even a favour of whatever you could imagine.
I add here that I have never heard of an individual instance of this. It is pure rumour. But I think it would be niave of me to not think that it does happen.
What do I do when a straight workmate who I flirt with and think is hot as, sends me an sms pleading for my shift? He was asking me to do him a favour and give him my shift so that he can attend a wedding. I replied that it did not suit me at all and but perhaps we could come to an arrangment. I phrased it a bit more frankly really, very frankly and specifically in fact. I knew he would not do it. I knew I would run a mile if he said yes (straight guys are just too hard work. I like guys who like guys as much as I do).
He sms back and politely declined.
I saw him three times subsequently. The first time he waved at me and the next two times, ignored me totally.
Oops, I went too far. No more flirting from him. No fun or nice chats.
Selfishness always overcomes pride. Today he sms me about another shift swap and this time it did suit me and I answered yes to him, without any bribe request. Formal agreement made.
Passes the time I suppose, no harm seems do have been done.
