I normally shuffle around to more comfortable seat like sofas etc around the office. I try to wfh at least one day. It's the employers responsibility to provide corrected posture on your chair but not all can provide this in which case youre on your own. A standing desk helps too. I've seen people just stack up boxes and make a makeshift standing desk. Back pain from work sucks and I'd recommend to not take this lightly.
