About the same depending on you trust/ local authority.
Nursing placements are shorter (4 - 8 weeks usually), social work placements are 30 days, 70 days and 100 days for the degree and 70&100 for the masters. So work out roughly the same number of days/ hours, just spread differently. There is a requirement for night shifts for student nurses, but there's significantly more night shift jobs in nursing than social work!
Certainly in Scotland, social workers are, after a few years qualified, paid quite a bit more than nurses. For instance, in my local authority, social work posts are advertised on a standardised salary of £34,264 - £39,762. Where you start within this depends on depends on experience. A similarly qualified nurse is on a standardised starting salary of between £25,100 - £31,649.
Also, only having to do 30 days for the first year and 70 days for the second year would be a dream for student nurses! 30 + 70 + 100 = 200 days. Assuming these are standard length days, 7.5, this would equate to 1500 hours over the course of the degree. Student nurses require 2300 placement hours to qualify however many unis make students go over and above this - at my uni, we did an extra 2 weeks, so 105 hours. It's intended to be a buffer should you miss placement days for any reason - I didn't miss any yet still had to do the extra hours as they are set as standard.
It isn't a competition but pay and conditions certainly aren't comparable between the two. I think both professions should be paid a lot more for the level of responsibility they hold and the hard work that they do on a daily basis! Both very undervalued professions.
