got covid on saturday, well sunday the symptoms appeared , rough as fuck, did a home test and it showed i had caught it again, bit worse than last time,still feel rough today, im due in work tomorrow, my quandary is, go into work(i've phoned work and they said treat it as a cold,if you feel fit come in) however my morals say i shouldn't go into work because i don't want anyone else to catch it ,however i would lose my bonus(£450, plus 3 days wages and it would go against my sickness record,too much money to lose ,but i don't want some else to get it who might be affected more , what should i do
